Answer: x=-1
Explanation:
x=-1
because
2x - 10
over = 3x
4
we can put everything in parentheses and multiply by 4
2x - 10
4( over )= (3x) 4
4
The 4's on the left side will cancel out around and leave
2x - 10
on the right we multiply 3x x 4 which equals 12x
rewrite the equation
2x - 10 = 12x
subtract 2x on each side with the variable.
2x - 10 = 12x
-2x -2x
the 2x's on the left will cancel out.
on the right 12x - 2x equals 10x
now the equation is
-10=10x
but we are not done
divide 10 on each side
on the left -10/ 10 equals -1 because one number is negative and that does not give a postive result.
on the right 10x/ 10 the 10's cancel out leaving the varible x
we are left with
x=-1
